Wilwood Electronic Parking Brake - Need photos of your installation

After looking at it some more, I might be routing the harness for the calipers with the same route as the rear side marker wiring.  This avoids running a new harness along the bottom of the car.

It looks like the switch for the EPB will get mounted where the cigar lighter currently lives.  It looks like the Wilwood engineers designed it that way.

Your thoughts on the harness routing and switch placement?

You may be aware of the routing of the taillight harness in the wheel well to clean up the engine bay…. Maybe you want to consider doing that, and routing the EPB wiring there as well, and just come through the marker light sleeves as needed to get to the calipers?

Yes, that is my thinking. The taillight harness is already rerouted out of the engine bay and into the passenger wheel well. The new EPB harness would piggyback on that.

Steve, as an alternative, you could mount the EPB switch in the hazard light switch location then relocate the hazard light switch to the cigar lighter location. You want to avoid any possibility of the EPB’s being activated accidentally and a curious passenger could create a very unsafe situation.

I mounted a Honda Starter button in the hazard light switch location and was surprised to find the hazard light switch fit perfectly in the cigar lighter hole.

I recently finsihed installing the Wilwood EPB.  I installed Recaro seats and Kirk Evans bulkhead reduction kit.  I had to remove the handbrake, there was no other way.  The Wilwood Electronic Parking Brake seemed like an obvious solution.  I mounted the Wilwood ECU on the firewall, passenger side, next to MSD-6AL and Tach Adapter.  Its getting crowded back there.

I didn't have to modify the wiring harness at all.  In fact I coiled up some of the extra length and may shorten it later.  I ran the switch wires along the AC lines behind the passenger seat and to the ctr console.  They are just long enough to place the switch in the cigar lighter hole.

I also spent far too long trying to get the dash light to come on when the parking brake was set.  The Pantera uses the handbrake to pull the dash bulb low, which is not the case in the installation instructions (provides +12).  Rather than rewire the light under the dash I used a second automotive relay to pull the original wire to ground.

Now I've lost my cigar lighter and wish I could trickle charge it through the lighter again.

JJones,

Are your mounting brackets for stock sized rear rotors?

The brackets change size depending on the rotor diameter and thickness.  Each combination may produce a different bracket.  I supply the drawing as a starting point.  I 3D printed the bracket a few times until I was happy.  Had them machined once.  The previous owner did the initial Wilwood rotor conversion, I don't have the docs.

A few more pics for the OP, routing wire on driver's side.  I used one zip tie to the SS brake cable.  Now I'm sure someone is going to give me 10 reasons not to do that.  If you have a better idea, please share your pics.

… but is the bracket in the drawing for a stock diameter rotor?  Is that the “starting point”?

The bracket was designed for 11.75” dia x 0.71” thick rotors.  - JJ

Thank you for the information. BTW, you probably meant 0.71” thick rotors.

I did.  I made the edit.  Thank you, J

All good info and photos.  It is much appreciated.

again.

That area is crowded in this car as well.  I'm not sure yet where it will land.

I finished installation of the Wilwood Electronic Parking Brake.  I was able to mostly conceal the wiring for the calipers and routed with the existing harness for the side markers and tail lights.  The red line is where the mostly concealed wire runs.

Looking very clean.  I may revisit my wiring to clean it up.  My son's wedding and veh inspection was in July so I was pressed to get the brake working.  I think I would like to move the switch out of the cig lighter and on the dash somewhere.  I cringe to think a passenger could unwittingly mess with it while I'm busy driving.  Modern cars probably disable the epb when the wheels are turning.

As I mentioned earlier in this thread, the hazard switch and cigar lighter occupy the same sized holes, so you can relocate the hazard switch to the hole previously occupied by the cigar lighter and put the EPB switch in the hole that the hazard switch previously occupied.

If your Pantera has EFI and a VSS, you can configure one of the ECU's outputs to disable the EPB at any speed you wish.   

Another safeguard would be to add a small switch in the console area that disables the parking brake switch.  When turned off it would prevent  a passenger from inadvertently locking up the rear tires.  It could also be used as a theft deterrent.  You could set the brake and then put the semi-hidden switch in the off position.
